摘要： In response to turning-on of a lock-type power switch (18, 22), an initial controller (19, 20, 21, 23, 26, 27) outputs a first voltage for a first predetermined period and a gate (13) is turned on for the first predetermined period via a first driver (16, 24, 25) responsive to the first voltage, so that DC power is supplied to a main circuit section (3). During the first predetermined period, a control processor (41) causes a voltage output section (50) to start outputting a second voltage so that the gate (13) is turned on via a second driver (17, 29, 30), and the DC power supply to the main circuit section continues. Once the power switch is turned off, the first and second drivers are disabled to turn off the gate, so that the DC power supply to the main circuit section is shut off. When no event has been generated for a second predetermined period, the second voltage output from the voltage output section is stopped to turn off the gate, so that the DC power supply to the main circuit section is automatically shut off. Once a power supply from outside over a power line (11a) is switched from an OFF state to an ON state while the DC power supply is shut off with the power supply switch kept ON, the power supply to the main circuit section is automatically resumed via the initial controller and the first driver.

摘要： Apparatus for providing electrical power to signal conditioner circuitry inside a musical instrument having a signal output jack mounted thereon to carry a conditioned music signal via a signal cable to a remote location. The power source is a battery mounted inside a housing that is part of a signal plug on the signal cable plugged into the signal output jack. The battery powers the signal conditioner circuitry while the signal plug is in the jack. The housing provides access to the battery. Alternatively, a rechargeable power source is mounted inside or otherwise on the instrument and is connected to the jack. A power supply first plug is inserted into the signal output jack to charge the rechargeable power source. After charging the power source, the first plug is unplugged and a second plug of a signal cable is plugged into the jack to carry the conditioned signal to the remote location. When the second plug is plugged into the jack, the charged rechargeable power source provides power to the signal conditioner circuitry.

摘要： When a first state signal is outputted from a latch circuit while a lid is open, a power control circuit turns off electricity supply to a main control unit based on the first state signal. On the other hand, when a second state signal is outputted from the latch circuit when the electricity supply to the main control unit is off, the power control circuit turns on the electricity supply to the main control unit based on the second state signal. Therefore, while the lid is open, even after the electricity supply to the main control unit is turned off in response to no operation being performed over the predetermined time, by operation of the second switch, the second state signal is outputted from the latch circuit. Thus, the electricity supply to the main control unit can be turned on without temporarily closing the open lid.

摘要翻译： 当盖子打开时从闩锁电路输出第一状态信号时，功率控制电路基于第一状态信号来断开对主控制单元的电力供应。 另一方面，当向主控制单元的电力供应断开时，当从锁存电路输出第二状态信号时，功率控制电路基于第二状态信号接通主控制单元的电力供应。 因此，当盖子打开时，即使在主控制单元的电力供应被响应于在预定时间内没有执行操作而被关闭之后，通过第二开关的操作，第二状态信号从锁存电路输出 。 因此，可以打开主控制单元的电力供应而不会暂时关闭打开的盖子。

摘要： For a given tone generating channel, tone waveform sample data corresponding to a plurality of sampling cycles (e.g., 100 samples) are arithmetically formed collectively. Once performance information such as MIDI event data is supplied to a tone generator MIDI driver (16) from an application program such as a MIDI sequencer software (31), the MIDI driver (16), in response to an input MIDI signal, assigns new tone generation to a designated tone generating channel of a tone generator task (20), and prepares tone controlling parameters to be set in the designated channel. The tone generator task (20) arithmetically forms tone waveform data by use of the tone controlling parameters and passes the tone waveform data to a CODEC circuit (26) functioning as an A/D converter. The program and a general-purpose operating system are sequenced and executed by a preemptive multitask management program.

摘要： An audio signal output from a tone generator 14 is fed into a coil 16 provided in a transducer for vibrating a sound board, so that a sound signal is generated by the vibration of the sound board. A microcomputer 30 obtains temperature values of the coil 16 measured by two different methods, and suspends supply of audio signals to the coil 16 or reduces the amount of audio signals supplied to the coil 16 if the difference between the two coil temperature values is outside a predetermined range. In a case as well where one of the two coil temperature values has risen excessively, the microcomputer 30 suspends supply of audio signals to the coil 16 or reduces the amount of audio signals supplied to the coil 16.
